THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 339,390, dated April G,1886.

Application filed November 23,1885. Serial No. 183,671. (No modeLl i Toall whom, t may concern:

Be it known that I, JOSEPH DEsMARAIs, of Lawrence, in the county ofEssex, State of Massachusetts, have invented a certain new and usefulImprovement in Carriage-Thills, of which the following is a descriptionsufijciently full, clear, and exact to enable any person skilled in theart or science to which said invention appert-ainsto make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure l is a vertical longitudinalsection, and Fig. 2 a top plan View.

Likeletters ofreferenceindicate corresponding parts in the differentgures of the drawings.

My invention relates more especially to means for preventing thecoupling from rattling; and it consists in a novel construction andarrangement of the part-s, as hereinafter more fully set forth andclaimed, by which a sinipler, cheaper, and more effective device of thischaracter is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explaneti on a lnthe drawings, A represents the axle, B the clip, and C the thill-iron.The clip is provided in the usual manner with horizontallyprojectingarms or brackets D, in which the iron C is journaled or `pivoted on thebolt E in the usual manner. The clip is also constructed with adownwardly-proj ecting screwthreaded stud, H, at either side of the axlein the usual manner, the studs being provided with nuts J.

In attaching the clip to the axle a clamping bar, K, provided with holesm is employed also in the usual manner, the studs H being inserted insaid holes, and the nuts J turned in onto the bar, thereby forcing itagainst the lower side of the axle and firmly securing the clip thereto.

In my improved thill-conpling I construct the bar K of steel, andelongate it to form a C-shaped spring, N, the spring and bar beingintegral or composed of one piece of metal. This spring is curvedupwardly and backwardly, its free end z being passed between the arms Dand bent around the inner end of the iron C, as best seen in Fig. l, thespring acting expansively and exerting a constant pressure on thethill-iron, thereby forcing it against the inner side of the bolt E andpreventing it from rattling in a manner which will be readily obviouswithout e. more explicit description.

In order that the bow m of the spring may drop low enough to be out ofthe way of the iron C when said iron is depressed, I cut out the axle Aon its under side, as shown by the dotted lines r, thereby elevating therear end of the bar K above the plane of its body and depressing the bowm accordingly. By this construction the clip Bis prevented from slippinglengthwise of the axle when the clip-bar is drawn up into the recess orcut-away portion thereof, and the bar K and spring N may be formed withor without an elbow or shoulder, as desired.

I ain aware that it is not new to clamp the clip-bar horizontallyagainst the bottoni ofthe axle and extend it into a spring, whether suchspring be given a bend at its point of connection with said clip-bar ornot; butin the presentinvention the clip-bar inclines downwardly towardthe front and rests in a recess in the under side ofthe axle.

Having thus explained my invention, what l claim is- In e thin-coupling,the axle A, provided with a recess in its under side inclined downwardlytoward the front, the clip B, having brackets D, and the thill-iron C,pivoted in said brackets, in combination with the clipplate K, adaptedto rest iu said recess, the C -spring N, integral with said clip plate,adapted to bear against the eye of said thilliron, and nuts J, forsecuring said clip-plate lin place.
